Jan 26 (Reuters) - Health insurer Coventry Health Care Inc CVH.N said its Chief Executive Dale Wolf resigned and Chairman Allen Wise was named as his replacement.
Last week, shares and call options on the health insurer rose on chatter that UnitedHealth Group Inc (UNH.N) could be readying for a bid.

Wolf's resignation is effective Jan. 30. In 2005, Wolf succeeded Allen Wise, who was the chief executive from 1996 through 2004.
